湖北荆宜高速公路b标a1段初步设计(附件)
本设计是湖北省荆宜高速公路B标A1段的的初步设计。设计主要包括公路选线定线、平面线形设计、纵断面设计、横断面设计、路面设计、道路排水设计及桥涵设计等几个主要部分。考虑到平原微坵地区地势较为平坦,路线走向起伏不大,本设计选用的路线为方案一,路线全长3039.634m,共设2处交点,管洞1个。平面线形设计包括直线以及各类曲线要素的确定,圆曲线采用的半径皆为1200m。纵断面设计要求确定竖曲线及其要素、以及涵洞布设位置等,最大纵坡值1.14%,最小纵坡为0.418%,共设5个变坡点,竖曲线半径最大值为2000最小值为5000。横断面设计包括路面宽度、路基的填高以及边坡的确定,还要考虑土石方调运问题,设计的路基宽度26m,路面宽度,18m。。路面设计主要是确定路面结构形式,并确定各结构层合理的厚度,本设计选用沥青路面,面层厚18(4+6+8)cm,基层为水泥稳定碎石,厚度340cm。底基层为级配碎石,厚度18cm。关键词路线设计,路基设计,路面结构设计,排水设计

Title Preliminary design of BStandard A1 section of JingYi
Expressway in Hubei Province
Abstract
This design is the preliminary design of the Bstandard A1 section of the JingYi Expressway in Hubei province.?The design mainly includes several main parts, such as Highway line selection, plane alignment design, longitudinal section design, cross section design, pavement design, road drainage design and bridge and culvert design.?In view of the plain Qiu area topography is relatively flat, the route to the ups and downs, the design of the selected route for the scheme one, the route length of 3039.634m, a total of 2 points of intersection, Pipe hole 1.?The plane alignment design includes straight line and all kinds of curve elements, the radius of the circular curve is 1200m.?The longitudinal section design requires to determine the vertical curve and its elements, as well as the location of the culvert, the maximum longitudinal slope value is 1.14%, the minimum longitudinal slope is 0.418%, a total of 5 variable slope points, the maximum vertical curve radius of 2000 minimum value of 5000.?The cross section design includes the road width, the roadbed fill high as well as the slope determination, but also must consider the earthwork allocation question, the design roadbed width 26m, the road width, the 18m.?Pavement design is to determine the road structure, and determine the reasonable thickness of each structural layer, the design of asphalt pavement, thick surface (4+6+8) cm, base for cement stabilized gravel, thickness of 340cm.?Bottom base is graded gravel, thickness is 18cm.
